Online pizza ordering systems are a way for customers to order their favorite food without having to wait on the phone. They also allow customers to browse for different types of pizzas and order them with just a few clicks. These systems can be found on many websites including Pizza Hut, Domino's, and Papa John's.

Online pizza ordering systems provide convenience for both the customer and the restaurant. Customers can order their food from home or work, while restaurants don't have to worry about phone lines being busy or employees taking too long with each customer.
